Default 1955 ford with 2 barrel ford carb

How do I determine what 2 barrel carburetor CFM ford used in 1955 on a 3 speed standard shift sedan ? The carb on the car is stamped Ford and is the Stromberg type two barrel, with a 3 hole base.
I am trying to determine what PCV valve I should use when installing a PCV system on my 55 sedan.
Also, if I install the PCV system in the valve cover instead of the valley pan cover would that work as good as if had installed it in the valley ????

There will be ID NOS stamped on the base plate of the carb. Can you post them?

You want to place the PCV valve at the rear of the valley pan as FORD did.

If it's the original type carb on your '55, then it's a Holley/Ford 2100 carb. It should be marked 1 1/16 on the back side about halfway up. That's the venturi size (1 1/16").
Guessing it flows between 200 and 225 CFM. The carb size isn't the determining factor in selecting the correct PCV. It's the cubic inch displacement. Get a PCV from a similarly sized newer engine (later than 1963).

Sal...the back of the carb 1/2 way up there is the numeral (1) would that represent 1 1/16 ??
When looking on line for a pcv valve, the 200-225 cfm engine are mostly 4 cyl with an occasional 6 cyl. ….would it matter that my engine is an 8 cyl 272 ?

Kultulz...there is nothing stamped on the "SIDES" of the base plate...can not tell if there is anything on the bottom of the base plate as the carb is still on the car.
As far as installing the PCV valve in the rear of the valley cover it would be a real tight squeeze. There is more area in the middle of the cover in-between the open sections of the intake manifold.
The valley cover has been sealed pretty well to the block with RTV by the previous owner and I am a little hesitant to remove the cover to drill a hole for PCV valve.
That is the reason I was thinking about using a valve cover instead. It would be a lot easier ...would the valve cover with the PCV valve installed be sufficient to relieve the pressure in the engine ?? Also would I have to install one in each valve cover using a tee to the carb base plate?

get a pcv valve for a 292 Chev. 6 cyl. it will be close enough. as far as putting the valve in the valve cover, you would have to fabricate a shield/baffle and weld it in to the inside of the valve cover in order to keep the pcv valve from sucking up to much oil

It doesn't matter 6 cyl. or 8 cyl. for a PCV valve donor. Do like Alaska Jim said. Match the cubic inches close with your engine. One for a Ford 289 V8 would be a good fit too.
If your carb has a "1" on it, then on the passenger's side of the fuel bowl, it probably says "EBU" which is for a '54 239 Y-Block V8. Possibly very early '55 272. It flows slightly less air than the 1 1/16" carb.

Default Re: 1955 ford with 2 barrel ford carb

Jim...looks like no matter what I do it will entail some work....my main purpose of installing the PCV valve was to take pressure of the rear seal....maybe I should just go with the Mummert valley pan with the rear hole already in place. Not a question of cost, more of a question of work.

Sal..did not see EBU anywhere on the carb....just the name Ford... believe the car was made in May 1955 in Somerville MA. Who knows what has been changed thru the years on these old cars...
THANKS FOR EVERONES HELP...…...

I described the ID incorrectly on this carb (have H4000 on my mind for some reason). I believe it (2100DD) came through with a separate ID TAG.

Sal should be able to clarify.

The early systems (FYB-FE-SBF) used a rear draw FOR A REASON. What you are describing came into play in 1965. The draw from a rocker cover will require a breather on the opposite side rocker cover to vent the top of the engine correctly.

To properly retro-fit a PCV SYSTEM to an earlier road draft FYB will require parts from the later 1960-1964 PASS CAR and/or LT 292 to function properly (IMO).

Default Re: 1955 ford with 2 barrel ford carb

If the main body of the carb has the FORD oval embossed on the side of the float chamber, it is probably an EBU which was used in all '54, 239 Y-blocks and some '55 cars with 272 Y-block and probably all '55 Ford F100's with 239. The opposite side of float chamber is stamped EBU. You will notice on the back of the main body is a circle with the number "1". That indicates it has 1 inch venturi's.
Probably most of the later '55 cars were equipped with the Holley 2100 instead of the old EBU. The Holley 2100 looks nearly identical to the EBU and is fully interchangeable without modifications to original linkage or air cleaner. On the back of the Holley 2100 main body is a circle with "1-1/16". That means it has 1-1/16 inch venturis.

Post Re: 1955 ford with 2 barrel ford carb

Below is the CARB ID CHART as shown in the MPC for the period. It plainly states that the ID can be found on an ASSY TAG, mounting flange and/or the carb body.

All of this is not rocket science. You need to figure if you want the car period correct or modified and then go from there.

A PCV ENGINE requires a splash shield/panel under the valley pan PCV valve opening. Most ALUM covers do not have this. The system will ingest splash and vapors through the system into the top end. In addition to cylinder fouling, the system will become less functional leading to excessive crankcase pressure and blow-by out of the filler cap, along with a few gaskets and seals.

I’ve used this grommet with baffle in the valley cover, worked fine with a stock motor. With the next stroker motor and supercharger, it wasn’t enough and I have to go with a welded baffle. It was solid on the side facing the distributor, the gear was apparently throwing enough oil at high rpm and boost that I picked up oil beyond what the rubber baffle could handle.

I had not realized what a project this PCV system would be...I do not want to create a problem by sucking oil into the carb.
What if any value is an oil fill cap with the pcv tube in it ?

The sealed oil fill cap with the tube out (I’ve not seen one for a PCV valve, doesn’t mean they aren’t out there) is to go to the air cleaner for a “closed” PCV system. I’ve used those.

The oil fill tube for a 69 Z28 has a bung for the PCV and is adaptable to the valley pan at the front. I’ve used those too. But it’s way more work than the grommet, or even the baffle on a stock pan. I like a closed system, it eliminates virtually all the blowby smell from the oil. Which air cleaner you’re using makes that easy or impossible.

Unless your running a high volume/pressure oil pump and winging it past 5000rpm, that grommet should work fine.

Post Re: 1955 ford with 2 barrel ford carb

Below is an ILL of a PCV SYSTEM as found on a later LT 4V application -




The pan must have a splash shield/baffle under the vacuum intake source (several styles of pans)-

The fumes are drawn into the adapter/separator (6A665) and then cooled in the tube (6758) where excess fumes drain back to the separator. The PCV valve is installed far from the vacuum inlet to help prevent contamination.

If one cannot find this system, either NOS or take-off, one must fabricate.

Just a clarification of how that grommet is designed -

There is a slit in the bottom of that closed grommet that will allow draw hopefully without ingesting vapors.

I'm pretty sure the part number ID tags on these carbs was just on service carbs from the dealer. Could be mistaken. The stamping of Holley LIST numbers and date codes was very sporatic back then. I've seen some stamped right above the venture size on the top cover, and some stamped on top of the bowl cover, but most had nothing. I don't think they got consistent with the part number stampings until the teapot 4 barrels arrived in 1953 on the Lincoln. Once again, this is just for the Holley 94 type carbs.

The TAGS had to be attached @ the vendor and then shipped to FORD ASSEMBLY. They were usually removed and not re-attached during service.

The APPLICATION CHART NOTE section will tell where to find the STAMPING ID on which particular carb. It seems location/style was not followed year to year. Maybe a rebuild kit sheet offers more info?
